To shown in Figure 10, wiring comprises upper case 101 and lower case 103 with the shell 101,103 of the formation outward appearance of circuit breaker 100 such as Fig. 3.In described shell 101,103 inside, fixed contact 7, moving contact 9, switching mechanism 10, tripping mechanism 8 and arc-extinguishing mechanism 11 are installed.On described fixed contact 7, possess fixed contact 7a and portion of terminal 7b, on described moving contact 9, possess moving contact 9a.And, on described lower case 103, possess for a plurality of outlets 5 of discharging the arcing gas that occurs when fixed contact 7a and moving contact 9a leave.
On the other hand, on described shell 101,103, wire frame 20 is installed.Essence, described wire frame 20 are installed on the terminal chamber that defines between a plurality of insulation wall 103a that described lower case 103 possesses.Described wire frame 20 can be formed by in opposite directions the open hexahedral shape of 2 faces roughly.And, any one in 2 faces of the opening by described wire frame 20, described fixed contact 7 and the electric wire 12 that is connected in described fixed contact 7 are access in the inside of described wire frame 20.
In the present embodiment, possesses projection 21 in the bottom surface of described wire frame 20.Described protruding 21 can be is roughly protruded downwards by the part of the bottom central part of described wire frame 20 and to form.And, on described protruding 21 bottom surface, possess the 21a of lead-in curve section.The described lead-in curve 21a of section can be formed by the curvature bending of having set by described protruding 21 bottom surface.Essence, the described lead-in curve 21a of section performance is inserted in the process of aftermentioned patchhole 7c described protruding 21, prevents the effect with the interference of described fixed contact 7.
And on described fixed contact 7, essence possesses patchhole 7c at described portion of terminal 7b.Described patchhole 7c is cut by the part of described portion of terminal 7b and forms.If described wire frame 20 inserts described terminal chamber, then described protruding 21 insert described patchhole 7c.
In addition, at described portion of terminal 7b, possesses guiding inclined plane 7d.Described guiding inclined plane 7d is installed on the direction of described terminal chamber to described wire frame 20, is provided to described portion of terminal 7b foremost.Essence, the direction that described guiding inclined plane 7d installs to described wire frame 20, the prolongation that is inclined upwardly, thereby the effect that performance guides the described wire frame 20 that is installed on described terminal chamber.
And, on described wire frame 20, link live wire fixed screw 30.Described electric wire fixed screw 30 comprises the section of exerting pressure 31, screw section 33 and connecting portion 35.The described section 31 that exerts pressure contacts with described electric wire 12 in the inside of described wire frame 20, the effect that performance is exerted pressure to described electric wire 12.Install above the described wire frame 20 of described screw section's 33 perforations.And described screw section 33 moves up and down with respect to described wire frame 20, and the described section 31 that exerts pressure is exerted pressure downwards.For this reason, described screw section 33 be incorporated into threadably described wire frame 20 above.Described connecting portion 35 performances connect the effect of described exert pressure section 31 and screw section 33.Certainly, also can delete described connecting portion 35, the lower end of described screw section 33 be directly fixed on the described section 31 that exerts pressure above.
The below further is elaborated to the assembling process of wiring of the present utility model with the 1st embodiment of circuit breaker.
At first, make fixed contact 7 be positioned at the inside of terminal chamber, make its part, that is, portion of terminal 7b is exposed.In this state, the wire frame 20 that combines electric wire fixed screw 30 is moved to the inside of described terminal chamber.
On the other hand, in the process that described wire frame 20 moves, the interference between projection 21 and the portion of terminal 7b may occur in essence.In the present embodiment, by means of the guiding inclined plane 7d that possesses on the 21a of lead-in curve section that possesses on described protruding 21 and the described portion of terminal 7b, the movement that can prevent described wire frame 20 is because of described protruding 21 and the phenomenon that is interfered of the contact of portion of terminal 7b.
In addition, if described wire frame 20 moves to the inside of described terminal chamber, be positioned at the position of design, then described portion of terminal 7b accesses the inside of described wire frame 20.In addition, if described wire frame 20 is positioned at the position of design, then described protruding 21 insert described patchhole 7c.Therefore, make described wire frame 20 under the state that is positioned at described terminal chamber interior, not mobile arbitrarily.
So be installed under the state of described terminal chamber interior at described wire frame 20, make the inside of the described wire frame 20 of electric wire 13 accesses.And, regulate described electric wire fixed screw 30, make described portion of terminal 7b and electric wire 13 fixing under interconnective state.
So, in the present embodiment, do not use the other connector such as screw and nut, can be by means of described protruding 21 and patchhole 7c, fixing described wire frame 20.Therefore, according to present embodiment, can fix simpler, more at an easy rate described wire frame 20.
With reference to the accompanying drawings, further 2nd embodiment of wiring of the present utility model with circuit breaker is elaborated.
Figure 11 shows that wiring of the present utility model is with the end view of the terminal frame of installing on the shell among circuit breaker the 2nd embodiment.For the inscape identical with above-mentioned the utility model the 1st embodiment inscape in the present embodiment inscape, quote the drawing reference numeral of Fig. 3 to Figure 10, and omit the detailed description to this.
As shown in figure 11, in the present embodiment, in a side of lower case 103, namely on insulation wall 103a, possess a plurality of mobile protruding 103b that prevent.Describedly prevent that mobile protruding 103b from the one side of in opposite directions described insulation wall 103a, protruding to the inside of terminal chamber respectively.Describedly prevent that mobile protruding 103b performance from preventing from being installed on the effect of wire frame 20 transverse shiftings of described terminal chamber.For this reason, if described wire frame 20 is installed on described terminal chamber, then the described protruding 103b of movement that prevents contacts the two sides of described wire frame 20.For example, comprise described prevent mobile protruding 103b at all or part of of interior described lower case 103 by having set flexible material moulding, for example, by the moulding of synthetic resin material, be installed in the process of described terminal chamber at described wire frame 20, describedly prevent that mobile protruding 103b can be subject to that described wire frame 20 is exerted pressure and strain.
In the category of this basic fundamental thought of the present utility model, for the person of ordinary skill in the field, certainly can realize other various deformation, interest field of the present utility model should make an explanation based on claims.
